If the whole of SF State seems to be on a perpetual sugar high, it may be because students are buying Girl Scout Cookies like they are going out of style.

The junior-ranked scouts that you see at the top of campus make an average $800 a day selling 200 boxes, said Troop leader Lannie Nguyen-Tang, an SF State employee whose daughter is a member of Troop 30227.

Nguyen-Tang has a lot of experience with sugar-happy students. She has been at the top of campus every day for three hours since the cookies went on sale. She has seen the girls through many sugar-highs.

She tells the volunteers that come with her to "blame it on the cookie."

The troop, which is supported by St. Anne's Church in the Sunset District, has 16 members.

"I want my troop to be diverse," says Nguyen-Tang, who said she has made an effort to get girls from many schools in San Francisco, both public and private.

"The best part of being a Girl Scout is meeting new people," said Lydia Tang, Nguyen-Tang's daughter. "I like getting to work with my troopmates."

The girls are selling the cookies to raise money for a charity of their choice and finance the trip to Hawaii they will take when they turn 16, said Madeline Quach.

Quach, 10, is trying to sell 1000 boxes of cookies to earn a Nintendo DS system. If a Girl Scout sells 1200 boxes, the prize is a Nintendo Wii system.

Tang has already sold 1200 boxes and is now working on selling another thousand to earn the Nintendo DS system as well.

Half of the members are attempting to sell 1000 boxes, so far five have reached the goal, according to Nguyen-Tang.

The girls and their parent volunteers join Nguyen-Tang at the corner of 19th and Holloway avenues.

They don't get there any earlier than 3 p.m. because of their school schedule.

"You can't take them out of school for cookie-child labor," said Nguyen-Tang.

This is 10-year-old Jacqueline Lee's third time selling cookies at SF State. She has been a Girl Scout for 2 years. Lee's favorite part of being a Girl Scout is seeing her friends but she also loves the projects they do.

"I liked the heritage family," she said. "I got to make my family tree." The heritage was a good opportunity for Lee to learn about her fellow students. Lee learned that some of her fellow scouts were adopted.

"I felt bad for them because they didn't know their [biological] parents," she said.

While it is true that the cookies are flying off the table, not everyone on campus is buying them.

Felicia Vasquez, an art photography major, hasn't purchased any, though she said she would like to.

"I gave up sweets for Lent because I'm Catholic," she said.

"I was okay with it until my friend pulled out a package of Thin Mints," said Vasquez, 22. "Then my heart broke because those are my favorite cookie."

Joel Balao, 22, has nothing holding him back from buying Dulce de Leche cookies, though Samoa cookies are his favorite.

"I buy them whenever they are available," said Balao, a pre-nursing major.

"Even though they are really bad for you, they are really, really good," he said.
